It is `Well known.that-tobaccorsmokefas itl leaves4` the bowl ofV a pipe carries considerable water vapor, vaporized'f'nicotines and lother `undesirable condens'ables. Inf the 'ordinaryrlpipe these' lcondensable materials collect inthe pipe stemv and bowl bottom'rwhere they' f'orm a disagreeable. and distastefulliquid which is `frequently drawn into the smokers mouth. -l\j/Ioreover, the smoke from.

an ordinary pipe has' a relatively high tempera-*-l ture, which togetherwithlthe condensa-bles causes the lsmoke'to bitethetonguefand mouth' ofv the y user. Y Y

I-have 'invented-a smoking pipe in which the smoke is cooled andthe water Vapor and other condensable materia-ls' condensed and collected l before the smoke reaches the smokers mouth'.

This produces a cool, agreeable-.pleasant smoke which has no tendency to Ybite the smoker-s tongue.

Generally, my invention comprises a bowl arid stem member inwhich Vthe bowl has a'lhollow, bowl-shaped interior `commf-mie'ating witlrA a longitudinalfbore the stem member. One end of therby-pass-means entersvthebore at a point adjacent the junctionof V.the bowl: and stem member and the other end enters the stem member near the end thereof. A reservoir means having a 'diameter-'substantially equal tof the bore: offthe stem member-extends into :the bore beyondthe point where the .by-pass means enters the bore near the end of the stem member. Means are also provided on the reservoir for tightly engaging the .by-pass means in the stem. A hollow bit means having a shank portion entering the reservoir is provided in the completed structure.

In the accompanying drawings illustrating a present preferred embodiment of my invention;

Referring to the drawings I have illustrated .a pipe' portion I in which the bowl portion 2 hasfa hollow, bowl-shaped interior` 3 communicating with a bore; 4in thestem member 5. One-end-G of a by-pass tubeI-enters they-bore throughg'an Y. opening t-8 in` the` stem -member adjacent the junction of thebowl 2.and stemmember 5. *Ther oDDOsite end Sfof moby-pass tube 1- enterslthefstem member 5 through. a slot I0.in `vthe stem member.

This rota-tionof the reservoir causes the.- bypass` tube'f tof bel twisted as shown in chain lines in'Figur'e there! by lockingnitinposition inthe stem member,'md reservoir.. A hollow bit ll'ihaving ashankv VIi'I is.

Whenth'e pipeis bein'gused, smoke 'generated by burn-ing tobacco fin' the: hollowbowl-shaped interior 3? :is 'drawn "linac-ik` intofthe .bo'r'e 4 or? the stem memberzrs wherezit islbldckedbytbe cap t3;-

on the end of the reservoir I2. The smoke then passes through the by-pass tube I Where it gives up its heat to the atmosphere through the` walls of thetube and the condensables such as water vapor are condensed onto the walls. Both the smoke and a large part of the condensate then pass into the reservoir where the condensate is collected and the smoke passes from the reservoir into the hollow bit I5 from whence it goes to the smokers mouth. When it is desired to empty the reservoir, the reservoir is turned to release the end 9 of the by-pass 'i which is then sprung upwardly to remove the end 9 from the path of the reservoir `which is then merely withdrawn from the bore, and emptied through hole I I or the screw cap I3 may be removed and the contents emptied from the reservoir.

By passing the smoke through the by-pass tube 1, a cool pleasant smoke, free of disagreeable condensables. is delivered to the hollow bit I5. The shoulder I1 on the shank I6 prevents any of the 3 condensate from running into the bit from which it might be drawn into the smokers mouth.

It should be noted that all of the parts t snugly but that the drawings are exaggerated to show a slight spacing between the parts. This exaggerated spacing in the drawings (Fig. 1) is i11- tended for purposes of clarity and not to suggest that a loose nt between the parts be used in constructing a pipe according to this invention.

It is readily apparent that the pipe of my in- .vention produces the cool, pleasant smoke that is so much sought after by pipe smokers. It is also readily apparent that this result is achieved by a simple, inexpensive but highly eicient structure that is easily produced. Y

Although I have illustrated and described a present preferred embodiment of my invention, it is to be understood that it may be otherwise embodied within the scope of the following claims.

I claim:

1. A smoking pipe comprising a bowl and a stem member having a longitudinal bore therein, said bowl having a hollow, bowl-shaped interior communicating with said longitudinal bore in the stem member, by-pass means one end of which enters the bore adjacent the junction of the bowl and stem member, a transverse slot in the stem member adjacent the end of said stem member through which the opposite end of the by-pass means enters the bore, rotatable reservoir means extending into the bore beyond the point at which said opposite end enters the bore, said reservoir means having an external diameter substantially equal to the diameter of the bore, an opening in said reservoir means to receive said opposite end of the by-pass means, a knurled end on said reservoir means extending above the external periphery of the stem member by means of which the reservoir means may be turned within the bore thereby locking the by-pass means in the stem member, and hollow bit means having a shank portion adapted to enter the reservoir at the knurled end.

2. A smoking pipe comprising a bowl and a stem member having a longitudinal bore therein, said bowl having a hollow, bowl-shaped interior communicating with said longitudinal bore in the stem member, by-pass means one end of which enters the bore adjacent the junction of the bowl and stem member, a transverse slot in the stem member adjacent the end thereof through which the opposite end of the by-pass means enters the bore, rotatable tubular reservoir means extending into and substantially filling the bore to a point adjacent the bowl and stem member junction end of the by-pass means, a removable cap on said reservoir means, an opening in said reservoir means to receive said opposite end of the by-pass means, a knurled ring on said reservoir means extending above the externalperiphery of the stem member at the end thereof by means of which the reservoir means may be rotated within the bore thereby locking the by-pass means in the stem member, and hollow bit means having a shank portion adapted to enter the reservoir at the knurled end thereof.

3. A smoking pipe comprising a bowl and a stem member having a longitudinal bore therein, said bowl having a hollow, bowl-shaped interior communicating adjacent its bottom with said longitudinal bore in the stem member, a thin-walled by-pass tube entering the bore adjacent the junction of the bowl and stem member at an acute angle with the stem member, a transverse slot in the stem member adjacent the end thereof through which the opposite end of the by-pass means enters the bore, rotatable reservoir means extending into and substantially lling the bore to a point adjacent the bowl and stem member junction end of the by-pass tube, an opening in said reservoir means to receive said opposite end of the by-pass tube, a knurled ring on said reservoir means, said ring extending above the periphery of the stem member at the end thereof by means of which the reservoir means may be rotated within the bore thereby deforming the by-pass tube and locking it in the stem member, and hollow bit means having a shank portion entering the reservoir at the knurled end thereof.
